Application led November 9, 1908. Seral'No. 431,626.

To all whom it may concern: f

Be it known that l, ltonnirr A. (l. ll'onz, a citizen of the, United States, residing ai, Cleveland, in the county of luyahoga and State oli Ohio, have, invented certain new and Useful improvements in Vaeutnn Apparatus ior llypereniie 'l`reatnients. of whieh the followingY is a speeitieation.

This invention relates to ilnprovelnei-its iu vaennin apparatus used partieularly for hyperetnic treatments One ot the objects of the invention is to improve, in a general way, thel etliciency and to extend the tield o use of such devices, and also to render their use more convenient hy the provision ot.E means whereby the air pninp-inay he. eonveniently attaehed to or disconnected from the vacnuni eup, and atthe saine time by doing away with the rubber tnhes which heretotore have heen used to connect the pumps and eups and by doing4 away with the expensive stop eoelts used in eonneetion with the tubes.

still further objet-.t4 is the provision oi means whereby the degree of vaeluun in the cnp may he readily varied at any time hm tore or atter .the pniup is removed 'troni the latter, so .that in rase it, is desired to lessen the degree ot exhaustion or vaenuni or to rerum'e the eup troni the hody of the pa.- tient, it will he nnneeessary to raise the cup troni the patientis holy to permit air toenter the cup.

.'lhe, invention relates, therefore, partienlnrly to the ctlp itself, to the means wherelnY it may he readily altar-hed to the pump, and to the provision ol'frertain valve 'features which will he lnought ont 'l'ully in the speeification. i

The invention may he hrietiy summarized as eonsistinin eertain novel details of eonstruction and e mihinations and 'arrangeneents ot parts, whieh will he described in the speeifeation and .set i'orth in the appended claims. l

For :1 better understanding` ot my invention relerence ishad to the accompanying drawing, in which-- Fig-ure 1 is an elevation ot' the vacuum apparatns constructed in aeeordanee with my invention. Fig. 9. is a` longitudinal sectional view of the Same. Fig. 3 is a transverse section on a slightly enlarged Scale, snhstantiallylalong the line. 3 v of Fig. 2. Fig. 4 isa View showing :i` cup and socket theretor, attaehed to the hotly oli' and diseonneetrd 'from the puuip.

liefert-ing now to the figures et the drawf ine'. ttt represents the vaeuinn eup whieh is made prelerahly of glass, :Sud whieh is' 'provided with an open end ll, and at. the opposite end with a nerlt .l havinga eentra'llylorntetl narrow pztssaifewa'y lf throueh which air is zulnii'tted to or exhauatetl Ytroni the cup, and haring an enlarged` end portion lil. Secured to the neeli ot the ont, is a shank or socket member ifi preferably r-,ylindrieal in shape and formed et metal and having'at one end a recessed portion lo whieh reeeires thc neck l? andis secured rigidly to the latter hy nieanel ot eententli' wliieh is ]nelieral l v waterproot, so that it will not he all'ected hy hot,- wnter when the device is heineY sterili'lzed. .-xt the opposite end ot the-shank or soelcet member l5 is a seeond reeess 1S which is threaded on the interior and is adapted to receive the threaded end ot' a pump to he re'lerred to later. lletween the two end reeesses it and the .shank l5 is provided with a passageway lt) which is in alineinent with the passageway l) in the neel; otz the cui and itornis a cona4 pat ient tinuation thereof. The end ot the passagel is tapered, aS

way lt) adjaeent the re shown in Fie. Q, and the: tapered portion AForms a seat t'or the tapered head otx a ping valve 2O which is preferahlyinade of rnbfl her and provided with a. shank which ex. tends down into the passageway. This plug valve is held vieldinpgl V down upon the seat prelerahly by means ot a spring` 2l shown in Fig'. El. i As will he explained later, by the provision of this plug valve, the pump can he removed from the shank or socket meinber and the air will nevertheless be prevented trom entering the cup.

ln order that the degree of vacuum in the,

eup may be readily varied, I have provided in the shank or socket member intermediate its ends. a release valve 22. For this pnrpose l have provided at the periphery of the shank or socket member a lng or boss 23 haring a centrally located passageway 24, the outer portion of which is threaded and receives the. shank of an adjustable screw or valve niernloer 25, and the inner end of which is profe restricted with respect to the onter portion and communicates with the inner passageway 19 which extends longitudinally of the. shank and communicates valve 36 is .formed by a lug 37 on the cup,

which air may be supplied or admitted to.-

the cup.V The admission of air through this .port is normally prevented by the adjustable screw or valve member 25, the inner end et the shank of which is tapered and is arranged to enter the restricted portion ofthe passageway 24.-.

Any suitable form of pump may be em ployed with the cup, but as here shown, the pump consists of a cylindrical casing or oylinder 27 which is provided with a piston 23 pivotally connected to a link 29 which in turn is connected to a crank 30 mounted in. the Wall of the casing and having on the exterior of the casing,` a portion 31 adapted to be grasped by the operator, so that when 4this portion. is revolved the piston will be reciprocated longitudinally of the casing or cylinder. The piston 28 is provided with a port 32 which is normally closed by a flap valve 33 secured to the surface of the piston and yieldingly heldwdovvnv/ard by a spring 34 so as to close the port. The end of the pump is provided with a threaded annular boss 35 which is adapted to be screwed' tightly into the threaded recess i8 oi the socket member l5.

In the present case l have shown at the bottom of the pump a release valve 36 similar tothe release valve 22 in the shank or socket portion of the cup. This release said lug having a passageway 38 which communicates with the interior of the pump, and the outerI end or' which is threaded and receives the shank of an, adjustable screw or valve member 39, theinner-end of which is tapered/and is arranged to close the passageway so as to prevent the passage oi air therethrough. As in the first instance, the lug is provided with a port ll() which communicates With the passageway on the interior of the lug. Thus it will be seen that when the air has been Wholly or par-4 tially exhausted from the cup, the pump may be readily removed 'from the latter and on account o' the valve, which is provided in the shank or. socket member, the removal of the pump will not in any Way change the degree of' vacuum in the cui A. single pump may, theretore, be employed with. a

large number of cups, any number of vvhioh may be attached to the body oi" 4the patient.

By doing away with the necessity for' theA rubber tubes which have heretofore been used, the device can be kept .in a .ni-uch more sanitary condltion, vand can be more readily sterilized. Also thev proper degree of vecuu um can be'moreeasily maintained the eup than when rubber tubes and stop eoelrs are employed.

monopoli.

The degree of vacuum in the cup can be very easily regulated, or the vacuum can be relieved entirely by the .release vulve 22 which l provide in the shank o1' sockel mouiber. rl`hus Awhen this valve is provided, it will not be necessary to raise the cup troni the body of the patient or to insert the lngers under the `end of thc cup adjacent the skin oli the patient to reduce the degree of vacuum or to remove the cup entirely.

The release valve .such as l have shown need not be provided in the pump, it all the oups are of the construction here shown, but l prefer to provide such. release valve in the pump, for the reason that the latter can then be used with cups which are provided with shank or socket members with or without the two valves here shown. .Also the release valve in the pump vvill be of utility in. some cases, such as when very small cups are ein ployed which could not be 'conveniently equipped with the valves, or `when the cup is intended to be applied to the body of .the patient for a very short interval only. ln the latter case there would be no necessity for removing the pump from the cup.

l do not desire to be Confined to the enact details shown., but aim in my claims to cover all modilioations which do not involve a departure fromL the spirit and scope of my invention. l.

Whatl claim as new and desire to secur by Letters Patent is l. ln a vacuum appara us of? the character described, a vacuum cup having` a n-eelr por tion., a shanli: or socket member secured thereto, said shank having a valve which is normally closed but which is automatilll() cally" opened When the airis being; exhausted 'from said cup, and said shank having a manually operable release valve intermediate said first mentioned valve and the cup.

2. ln a vacuum apparatus of' the character desoriloed, a vacuum cup open at one end and having .a necir portion, a shank or socket member having at one end a recessed por tion which receives the neclr portion and is rigidly secured thereto, ari air pump adapted to be attached directly to the opposite end ci. said shanlr or soclret member, said shank having a valve which is normally closed but is automatically opened byl the pumping of the air from the cup, and said shank having a manually operable release yalve'interniediate said l'irst named valve and the cup: ,4

3. lin combination, in a vacuum apparatas, a vacuum cup having' an open end and a noch' portion at its opposite end, a

shank or a socket member reoeivingR said neolr portion anelrigidiy secured thereto,

lila

said shank having an interior opening or passageway which communicate; with the interior et' the cup, a tapered valve seat at i the outer end et esaid passageway, a valve :incase plug normally engaging said seat and serving to retain the vacuum in the cup when the an' is exhausted from the same, and-said shank having a release valve, said release valve comprising, a transverse passageway which communicates with the inner. passageway or opening in the shank, an air inlet port communicating with said transverse passaoeway, and a screw valve member are ranged to close said transverse passageway and to permit the passage of air to said Cup when shifted from its normal position.

4. In combination, in a .Vacuum apparatus, a cup having an ope-n end and a-neck gort-ion, a shank or socket member receiving said neel: portion and rigidly secured thereto, said shank having a centrally located passageway which eommnnicates with the interior of the cup, the outer end of said passageway forming a valve seat, a movable valve member normally engaging said seat,

a manually operable release valve at--the side of said shank, said release Valve comprising a transverse passageway which com-` way, al'movable valve member in the' form@ of a screw which when in its normal position prevents the passage of air through said port, an air pump, the ends of said shank or socket member and the pump having cooperating threaded portions whereby the pump may be rigidly secured to the socket member. f

In testimony whereof I aiiix my signature in presence of two witnesses.
